Musically, the goal of the live show is to more or less remix the exisitng material, presenting it in a way that's familiar but also different. In other words, if you've heard "Fellow Prisoners", you'll recognize the songs. But they won't be the same songs exactly. Some are structurally similar to the album version, some are not.
There are a few reasons I'm taking this approach. One is to make the set a different experience from the CD. That's hardly a new concept, lots of bands do that. But it also gives me a chance to exorcise a few demons. For example, some of the material on "Fellow Prisoners" is pretty old. "Wellington" for example dates back to 1998. I'd like to think I've evolved a little since then, so the approach to "Wellington" is different live. Also, there are elements of some songs on "Fellow Prisoners" that tend to make me wince, hearing them now. So those elements go away. And, in the process of translating the songs to a live context, some new ideas come up that seem worth exploring.
